INGOT-TRIMMING PRESS.

Application filed October 5, 1923. Serial No. 666,787.

This invention relates to trimming ma chines and has for its object the provision of a novel device for removing all surface,

flaws and seams from iron or steel bars, billets, ingots and the'like so that the billet or ingot will be in proper condition to'be passed tothe rolling mill.

An important and more specific object is the provision of a machine of this character which is equipped with a screw operated power driven plunger for forcing the bar or ingot through a plurality of vertical and horizontal cutters which are constantly rotated and which operate to remove surface imperfections.

Another object is the provision of a machine of this character in'which spray means is provided for cooling the cutters during their action and thus preventing them from becoming'overheated to such an extent as to destroy the temper.

Still another object is the provision of a novel means for adjusting the various rollers toward or from each other depending upon the size of the bar or ingot and dependingupon the depth of cut desired, othermeans being provided for positively centering the various cutters. j

A further object is the provision of guide rollers through which the bar or ingot passes after leaving the cutters, these guide rollers being also adjustable to correspond with the positions of the cutters.

An additional object is the provision of a machineofthis type which will be comparatively simple in construction, easy to control and operate, eflicient in action, durable in service and a general improvement in the art.

With the above and other objects and" ad vantages in view the invention consists 111 the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the complete machine,

Figure 9 isa vertical section on the line 99 of Figure 3, I

Figure 10 is a section on the'line 10-'1O of Figure 9, and i Figure 11 is a detail section 1l11 of Figure 1.

on the line Referring more particularly to the drawings have shown my device as comprising a mam supporting frame or base 20 upon which is mounted the auxiliary frame member and superstructure needed for supporting the various elements of the mechanism. This structure includes, in part, upstanding frame members 21 which carry the various cutters and guide rollers to be'described, and in advance of these frame members" is a guide casing 22 within Which is placed the billet, bar oringot to be trimmed, and this cas ng is provided with a hinged cover or door 23 permitting access to the interior, the door being equipped with suitable hold-. ing means for maintaining it closed when desired. i

The means for moving the bar or billetv along this casing consists of' an elongated shaft 24 which is threaded to define a. plungier screw and which is slidable through guides 25 on the main frame. Screwed onto this shaft but restrained from longitudinal movement with respect thereto is a worm wheel current and the motor is a cut off switch31 i which includes a movable element 32' disposed in the path oftravel of a stop 33 carried by the s aft 24. so that when the shaft has been moved to the maximum extent desired the engagement of the stop 33'with the element 32 will cut off the' Current; If preferred, this'stop arrangement might be used for automatically reversing thevmotor at the en'd'of the movement of the feed; screw I shaft.

In advance of and eithersecured to or formed integrally with the frame members 21 is a frame 34!; f0rmed with horizontal guides 35 and 36 within which are slidable ings 37 and 38 are upright shaft-s '39 which' carry cutters 40. On the lower ends of these shafts are beveled gears 41 which mesh with beveled gears 42 on a horizontal shaft 43 driven in any desired manner. The shaft 48 is the main drive for the entire mechanism and is here illustrated .as equipped with a gear 44 with which meshes a pinion 45 on the shaft 46 of an electric or other motor'47. The gears 42 are splined upon the shaft 43 so as to permit sliding movement when the bearings 37 and 38 are adjusted by the means to be described, and the gears 41 and 42 are held always in mesh owing to the provision of arms 48 which depend I from the bearings 38 and which slidingly enga e upon the shaft 48.

or eifecting adjustment of the cutters 40 toward or from each other, I provide upper and lower, horizontal screws Y49 and 50 associa'ted respectively with the guides 35 and 36. These screws have their end portions oppositely threaded so that when they are rotated in one directionthe bearings through which they pass will be movedjtogether and when they are rotated in the opposite direction thefbearings will be moved apart. One screw, the lower one 50, is here shown as equipped with a hand wheel 51 by means of which 'it may be turned and both screws carry sprockets 52 about which is trained a chain 53 which operates to turn the upper screw when the lower one is turned manually. y H

'QIt is'important that means be provided for bringing the center lines of these cutters .in exact alignment and to-accomplish this I make the bearings 37 and 38 of a peculiar construction 'so as to embody a movable section'engagedby set screws 54 equipped with lock nuts 55. This adjustment of thebearings'is independent of the above described double ended screw adjustmentand is only for the purpose of insuring alignment of the centers, the first described adjustment being provided for varying thedistance between.

the cutters for working upon ingots or billets of different sizes or for regulating the depth of cut made by the rotary cutters.

' The frame members 21 are formed with vertical guides 56 within which are slid-able pairs of bearings 57 which are very similar in construction to the bearings 37 and 38 and which carry horizontal shafts 58 on g which are mounted rotary cutters '59 which are for trimming the top and bottom surfaces ofthe bar oringot. On the ends of the shafts 58 are beveled gears 60 which mesh with beveled gears 61 splined' on a vein tical drive shaft 62 which is equipped at its lower end with a beveled .gear 63 meshing with a beveled gear 64 on the main drive shaft 43. The splining of the gears 61 on the shaft 62 permits the gears 60 and 61 to remain always in mesh regardless of the adjustment of the bearings 57 and the bearings carry arms-64. engaging the gears 61 for holding them in mesh with the gears '60. The adjusting means in this instance consists of; vertical screws 65 located within the guides 56'and' having their end portions op- Forconducting the bar or 'ingotthrough the entire device, I provide a set 'o'f guide rollers which are adjustable "to correspondto the adjustment of the cutters. This feature includes the provision of frame members or portions 69 located rearwardly of the frames 21 "though they may be formed integrally with these frames 21 if preferred, such details being immaterial. The frames or framefportions 69 are formed with vertical 4 guides 70 within which are slidable bearings 71 carrying shafts 72 on which are rollers 7 3. The bearings 71 are held 'in adjusted position byscrews 74 j'ournaledin the upper and lower portions of the frames'69 and threaded through the bearings 71. The frame structure 69 is also formed with horizontal guides 75 within which are slidablebearings, 76 carrying shafts 77 on which are mounted vertical "rollers 78. ,Screwed through the frame are other screws 7 9 which are threaded through. the bearings 7 6 for adjusting the vertical rollers toward or from each other. j V

In the operation the hot" ingot, bar or billet is placed within the casing "22 and the door 23'is closed. The motor 29 is set in operation and acts "to rotate the worm wheel screw plunger 24. This plunger enters the casing 22, engages the bilet or ingot and forces it between the constantly rotating vertical cutters 40 and horizontal cutters 59.

'26 whichacts as a nut for advancing the lln All the cutters positively rotate iniopposition to the travel of the bar or ingot and consequently they operate to remove all surfaceroug'hnesses, fiaws,.seams and other defects so that the billet or ingot willbe in proper condition to be conducted Itothe rolling machine where'its size is to be reduced in the-usual manner. As there is danger of i of water power is connected with the pipes.

After leaving the cutters, the trimmed bar or ingot passes through the set of horizontal and vertical rollers 7 3 and 78 and then to whatever rolling machine is used. The various adjustment features have been described above and a reiteration is believed to be unnecessary, It might be Well to state that the guide rollers hold the billetin a true position while the first set of cutters are in operation. The guide rollers also act as a guide for the nose of the bar or billet to convey the same in-a true and straight subsequent treatment.

line to the last set of cutters, the rollers also acting to hold the bar or billet against switching either up, down or side ways while the cutters are effecting or exerting their trimming action.

From the foregoing description andv a study of the drawings it will be apparent that I have thus provided a simply constructed and very easily controlled and operated machine which will most effectually trim ingots and the like ready for Practically every contingency has been anticipated and adjustment and compensation allowed therefor so that the device should be capable of performing its function in a most highly satisfactory manner.
